With Qt in linux picking up and passing data from a buffer legible in linux
and RTL both, there is opensource freeware by David Christini at

Various versions use various RTL and linux (and Qt) versions; C++. His realtime
data comes into the buffer from DAQ cards; Comedi provides the drivers.
Qt's signal-slot mechanism passes the info into the right places. Does anyone
know of other ways to do that?
